TECHNICAL FIELD

The present invention relates to a device capable of preventing a sole of a wearer putting on shoes from slipping in the shoes, and more particularly, to a combination of socks and shoes for preventing slip of a wear's sole, in which a shoe insole is formed with a groove, and a sock of the wear is provided under a bottom thereof with a slip-resistant plate formed with a protruded portion corresponding to the groove, so that the sole of the wearer does not unnecessarily move in the shoe by the engagement of the groove and protruded portion.

BACKGROUND ART

The present invention is helpful to achieve a user's aim by applying the basic principle of the present invention to sporting footwear and thus allowing the user to conduct correct motion. For example, golf is a sport requiring a precise shot, a strong physical strength, and concentration, in which a golf ball is not moved in a purposed direction by any little mistake. The golf uses dedicated supplies, i.e., a golf shoe, as well as other sports. The golf shoe is generally provided under an outsole thereof with spikes, so as to prevent the slip of a wearer. Although the wearer puts on the golf shoes designed for a specific purpose, it is not possible to prevent slip of a wearer's sole from slipping in the inside of the golf shoe. Specifically, in case of striking a golf ball on an inclined ground, the slip of feet do not prevent in the internal space of the golf shoe, even though the outsole is fixed to the ground.

In case of other sports shoes or running shoes, the outsole contacted to the ground is made of various kinds of material and is design in various shapes to prevent the slip. However, there is no means for preventing the wearer's sole for slipping in the shoe.

In particular, uppers used in sports shoes, such as golf shoes, running shoes, tennis shoes or the like, are generally made of polyol resin having light weight, good air permeability and durability. Since the polyol resin has a strength lower than that of the uppers made of natural or artificial leather, more wide space allowing the movement of the wearer sole is generated in the inside of the shoe. Therefore, it is more required means for preventing the slip of the sole.

DISCLOSURE OF THE INVENTION

Therefore, an object of the present invention is to solve the problems involved in the prior art, and to provide a combination of socks and shoes for preventing slip of a wear's sole, in which a shoe insole is formed on an upper surface thereof with a plurality of grooves, and a sock of the wear is provided under a bottom thereof with a slip-resistant plate formed with a protruded portion corresponding to the groove, so that the sole of the wearer does not unnecessarily move in the shoe by the engagement of the groove and protruded portion.

In order to accomplished the above-mentioned object, the present invention provides a sock including a slip-resistant plate at a lower surface of the sock, the slip-resistant plate provided with a protruded portion continuously or discretely formed in a horizontal or lengthwise direction on a lower surface of the sock. In addition, the present invention provides a shoe including an insole formed with a plurality of grooves s provided on an upper surface of the insole, the grooves being continuously or discretely formed in a horizontal or lengthwise direction such that protruded portions of a sock are engaged to the corresponding grooves to prevent a wearer's sole from slipping.

BEST MODE FOR CARRYING OUT THE INVENTION

Reference will now be made in detail to preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

A sock of the present invention will now be described with reference to FIG. 1, in which FIG. 1 is a cross-sectional view showing the sock according to a first embodiment of the present invention. As shown in FIG. 1, the sock A of the present invention is formed in a general sock, and includes a slip-resistant plate 10 adhered to a lower external side of the sock. The slip-resistant plate 10 is made of solid material having low elasticity, which is different from a synthetic fiber that is a main component of the sock. In other words, molten synthetic resin is adhered to the external side of the sock. The slip-resistant plate 10 has a continuous or discrete protruded portion 15. The protruded portion may be formed in a horizontal direction, a lengthwise direction or a combined horizontal/lengthwise direction. Preferably, the protruded portion 15 is integrally formed with the slip-resistant plate 10.

The slip-resistant plate 10 is formed with a plurality of vents 17 at a flat portion except for the protruded portion, so as to ventilate in the sock. Even though the user wears the sock A, the air flow may be generated through a bottom surface of the sock by the vents 17.

A second embodiment of the present invention will now be described with reference to FIG. 2, in which FIG. 2 is a cross-sectional view showing a sock according to the second embodiment of the present invention.

As shown in FIG. 2, the sock according to the second embodiment of the present invention includes a plurality of divided slip-resistant plate 10 adhered to a lower external side of the sock A. Contrary to the first embodiment that the protruded portion is formed at one slip-resistant plate, the slip-resistant plate 10 according to the second embodiment is provided to the external side of the sock at a desired position as a separate component. In other words, the slip-resistant plate 10 according to the second embodiment is formed in a rectangular shape and servers as a protruded portion itself. Also, the slip-resistant plate 10 may be continuously or discretely formed in a horizontal direction, a lengthwise direction or a combined horizontal/lengthwise direction.

A sock according to a third embodiment will now be described.

The sock according to the third embodiment includes, as shown in FIG. 1 or 2, a coating layer 20 for directly contacting the wearer's sole with a portion of a bottom surface of the sock to prevent the slip. Specifically, the sock is provided at the lower external side thereof with the slip-resistant plate 10 and the protruded portion 15, as the first embodiment, and is formed with the coating layer 20 at the internal bottom surface of the sock. As shown in the second embodiment, the sock A is provided with a plurality of separate slip-resistant plates 10, and a plurality of separate coating layers 20 are formed in the inside of the sock.

The coating layer 20 is made of a natural rubber or synthetic resin and is coated in a thin thickness to provide a recessed portion, as shown in FIG. 1. The coating layer 20 is to prevent the slip of the sole, while the recessed portion is to provide an acupressure effect. The coating layer 20 is formed with a plurality of fine vents 25 to provide the air flow through the bottom of the sock.

In addition, as shown in FIG. 2, a plurality of separate coating layers 20 are formed in the inner side of the sock. In other words, the coating layer is protruded in a convex shape to provide the acupressure effect.

A shoe according to the present invention will now be described with reference to FIG. 3, in which FIG. 3 is a cross-sectional view showing a shoe according to the first embodiment of the present invention.

The shoe according to the present invention includes an outsole 30, a midsole 40, an insole 50, and an upper 60, as conventional shoes. According to the present invention, the insole 50 is provided on an upper surface thereof with a plurality of grooves 55. The grooves may be continuously or discretely formed in a horizontal direction, a lengthwise direction or a combined horizontal/lengthwise direction.

FIG. 4 is a plan view of the insole 50 having grooves 55. The insole is formed of pylon or urethane material, the grooves are formed when shaping the insole.

The shapes of the grooves 55 indicated by reference numerals a, b, c and d in FIG. 4 are merely one example, and may be modified in various shapes.

The cooperative relationship between the sock and shoe as described above will now be described.

FIG. 5 is a cross-sectional view showing the engaging state of the shoe having the insole formed with the grooves and the sock having the protruded portions. In other words, the figure shows the state of the user wearing the shoe over his/her sock.

As shown in FIG. 5, when the user wearing the sock A according to the present invention puts on the shoe B having the insole 50 formed with the grooves 55, the grooves 55 formed in the insole 50 are accommodated with the protruded portions 15 formed at the lower surface of the sock A. In the state that the protruded portions 15 are inserted into the corresponding grooves 55, the wearer's sole does not move or slip in any direction within the shoe.

Preferably, the described shoe and sock are provided in a combination product, so that the grooves and protruded portions are easily engaged to each other.
